    Default Pop3 Ssl

    Hi Guys,

    getting asked awkward questions by a third-party company who needs to access our Zimbra using POP3.
    Obviously we use IMAP 99% of the time and I have never thought much about the POP3 aspect of Zimbra.

    This company is asking to be able to send mail to us for an auto-responder on our Website hosted with our ISP. They need a POP3 address to send temporary message to and it must to an address with the same domain suffix as our website. This domain suffix is pointed straight at our Zimbra server on-site.

    So basically I need to set up POP3 on Zimbra for them, the box for POP3 is already ticked on the Zimbra Admin interface but if we are going to have to use it I would like to force them to use POP3 over SSL.

    They have now come back to me saying they are happy to do this but that I need to install two Pearl modules, Mail::POP3Client and IO::Socket::SSL.

    I have checked using http://*domainname*/cgi-bin/arp3/arp3-modules-ssl.pl and these modules are not showing as installed but is this just because I need to look somewhere else for Zimbra Pearl modules?

    Does any of this make much sense to you Guys as it doesn't make a lot of sense to me?!

    Thanks for any help
    Russ

    Why do you think you need to install those perl modules? Have you checked the "Enable SSL for POP3 service" option in the admin UI?

    Hi,

    yes I have indeed ticked it.

    That's why I'm stuck, as far as I'm concerned it's ready to go, it is just the company saying I need these.

    Thanks

    There should be no reason why you need them as far as I know, have you tried connecting to a mailbox via POP3S and does it work? If it does then that should be sufficient.

    Hi Phoenix,

    if you are sure that it should work then I suspect it's them misunderstanding or simply a firewall issue for us since I have never tested it before.

    I'll give it a go from home tonight.

    Thanks
    Russ

    If you want to send me the details of a test account I'll try it now for you.

    There's definitely the possibility of a firewall issue. Have you checked that port 993 (which is the SSL POP port) is open on your firewall? Have they on theirs?
    Cheers,

    Hi,

    surprisingly I had actually remembered to open port 993! Got port 995 open too.

    Don't remember doing it though, must have been years ago!

    This is the reply the company sent me this morning;

    As I wrote in previous email you need
    Mail::POP3Client and IO::Socket::SSL Perl-modules installed
    to allow a Perl-script accesses mail.*domain*.co.uk with port 995.

    These 2 modules are absent at your server and we can't check this.
    http://*domainname*.co.uk/cgi-bin/ar...modules-ssl.pl


    I will try to send you some details Phoenix when I can work them out for myself!

    Thanks again Guys
    Russ

    Hi Guys,

    sorry, still having issue with this!

    First of all, thanks for your help Phoenix.

    POP3 SSL access to our Zimbra server is now working perfectly for me, I can access it from outside our Firewall and see my mail, however the third-party company mentioned previously is still insisting I need the Perl modules installed.

    I'm guessing I should not install these from CPAN and that they would have no interaction with Zimbra if I did, so what do I tell them?

    There is nothing wrong with Zimbra over this as far as I am concerned just need a little advice on how to deal with the situation.

    Thanks
    Russ

    I don't understand several things about this (nothing new there). Why do they insist you install these packages on your server? How are they connecting to your server to get their mail? Are they actually unable to access your server cia pop3s and what errors do they see? As you've already said, you can access the pop3s service without those modules, I don't see why they insist you install them.
    Regards
